Before you choose.

Which airflow figure should you compare?

Use the same CADR particle type and units. A value without a named particle type stays separate from smoke, dust and pollen ratings.

How was the room size calculated?

A larger advertised room may assume fewer air changes per hour. Read the area and ACH together, and check ceiling-height assumptions.

What will the filter need?

Check the replacement model, recommended maintenance and purchase options. Filter subscriptions and specialty filters may be separate.
